SPECIFICATION forming part of Letters Patent No. 777,609, dated December13, 1904.

Application filed October 25, 1902. Serial No, 128,691. \No model.)

To all whom, it may concern:

Be it known that I, ROYAL E. DEANE, acitizen of the UnitedStatesresiding at New York, in the county of New York and State of NewYork, have invented certain new and useful 1m provements inReceptacle-Covers, of which the following is a full, clear, and exactspecilication.

This invention relates to receptacles for containing fluids underpressure, and has for its object to provide a cover for such receptacleswhich can be quickly put in place and removed and which is simple inconstruction and composed of few parts.

It comprises, broadly, a cover adapted to pass through the orifice andfitting under a flange on the receptacle and to be held by the interiorpressure.

By this invention the use of mechanical i'astenings and gaskets orpacking is done away with.

Heretofore receptacles of this class-s uch as sterilizers,water-heaters, &c.have been constructed with sliding or hinged doorswith mechanical means for fastening the same in place, necessitating theuse of many parts and of packing materials to make tight joints. Withsuch constructions the operation is slow and it becomes difliicult tokecp them clean. In my construction the parts are reduced to a minimumand access to the interior of the receptacle can be readily had.

Reference being had to the accompanying drawings, Figures 1, 2, and 3are cross-section views of portions of receptacles provided withdifferent forms of my invention. Fig. 4 is a plan View, on a reducedscale, of the conical cover shown in Fig. 1. Fig. 5 is a plan view ofthe flange shown in Fig. 1. Figs. 6, 7 and 8 are detail plan views, on areduced scale, of parts shown inFig. 2. Figs. 9 and 10 show ways offorming the flange.

Referring to Fig. 1, A is the receptacle, having an open mouth. Attachedto the top of the receptacle A is a conical flange or annulus 1. 2indicates a detachable conical cover larger in diameter than theopening, having a handle 3 and composed of resilient material fittingclosely against the flange 1.

In this form the cover is made of resilient material, so that afterbeing pushed through the apertureit will resume its normal conical form.It is held in place by the handle until the interior pressure becomessuflicient to retain it.

In Fig. 2 the cover is made in two parts. The central portion 2-1 ismade of rigid material and is smaller in diameter than the opening inthe receptacle. In order to retain the central portion in place againstthe interior pressure, an auxiliary ring 1, of resilient material,preferably copper, is used. This resilient ring is larger in outsidediameter than the opening and smaller in inside diameter than thecentral portion. These two parts are operated together in the samemanner as a one-piece cover.

In Fig. 3 I show a form similar to that shown in Fig. 1, the flange 12and cover 22 being only slightly conical, so that they can engagefrictionally by a slight outward pull on the handle 3. The cover 22 isdepressed, as shown, so as to give rigidity and prevent buckling.

It is obvious that the form shown in Fig. 3 could be applied to theconstruction shown in Fig. 2 by simply changing the slant, so that theauxiliary ring, central portion, and flange would frictionally engagewith each other and be retained in place.

I have shown various ways otforming the flange. In Figs. 1 and 2 it isriveted 011, in Figs. 3 and 9 it is integral with the receptacle, whilein Fig. 10 the top oi the receptacle is turned over and the bottom ofthe flange correspondingly turned over, so that they can interlock.

I do not desire to limit myself'to any particular construction ofreceptacle or of cover or of flange, as my invention is susceptible ofmodifications and may be applied to various kinds of receptacles -forinstance, the flange may be resilient.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. A receptacle having an opening, a cover larger in all diameters thansaid opening, and resilient means located at the junction of the coverand receptacle which can be distorted to permit the cover to passthrough the opening, said resilient means resuming its normalshape afterthe cover has passed through whereby the cover closes the opening fromthe inside of the receptacle, substantially as described.

2. A receptacle having an opening, a cover larger in all diameters thansaid opening, and having a separable, resilient outer portion, wherebythe cover can be distorted to pass through the opening so as to beretained against interior pressure, substantially as described.

3. A vessel comprising two parts, a receptacle having an orifice, aflange having a conical bearing-surface surrounding said orifice, and aseparable, conical cover of material adapted to withstand pressure, saidcover being larger in diameter than said opening, one of said partsbeing resilient in part to permit the cover to be inserted through theopening, substantially as described.

4. In a receptacle, having an opening,a cover larger in all'diametersthan said opening, and having a resilient coned portion which can bedistorted in order to enable the cover to pass through the opening,substantially as described.

5. A receptacle having a circular orifice, a cover larger in diameterthan said orifice, said cover comprising a central portion smaller thanthe orifice and a conical resilient ring larger in outside diameter thanthe orifice and smaller in inside diameter than the central portion,substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

ROYAL E. DEANE.
